RT6310E/EH

10A, 23V Synchronous Step-Down Converter with 3.3V LDO

General Description

Features

⚫ Input Voltage Range

The RT6310E/EH family are high efficiency

synchronous step-down DC-DC converters with pseudo

constant switching frequency 500kHz and deliver up to

10A output current. The RT6310E/EH operate from

4.5V to 23V input voltage. The output voltage of

RT6310E/EH is fixed to 3.36V output voltage.

 RT6310E/EH: 4.5V to 23V

⚫ Output Voltage

 RT6310E/EH: 3.36V

⚫ 10A Continuous Output Current

⚫ Stable with POSCAP and MLCC Capacitor

⚫ Fast Transient Response

The RT6310E/EH adopts Advanced Constant On-Time

⚫ Diode Emulation Mode (DEM) for Power Saving

⚫ Ultrasonic Mode (USM) for Avoiding Acoustic

Noise

(ACOT ) control architecture that provides ultra-fast

transient response and further reduces the external

component count. In steady states, the ACOT

⚫ Pseudo Constant Switching Frequency 500kHz in

CCM

operates at nearly constant switching frequency over

line, load and output voltage ranges and makes the EMI

filter design easier.

⚫ Internal Power MOSFET Switch 17m (high-side)

and 7.5m (low-side)

By setting the voltage of the EN/MODE pin,

RT6310E/EH operates either in diode emulation mode

(DEM) or ultrasonic mode (USM) at light load. The USM

maintains operation frequency above 25kHz, which

eliminates the acoustic noise. In the DEM, RT6310E/EH

provides the best light-load efficiency and improves the

acoustic noise with spread spectrum function.

⚫ LDO

 RT6310E/EH: 3.3V/100mA

⚫ Overcurrent Limit

 RT6310E/EH: 15A

⚫ Output Under-/Overvoltage Protection (UVP/OVP)

 RT6310E: Latched Mode UVP/OVP

 RT6310EH: Hiccup Mode UVP and Non-Latched

Mode OVP

RT6310E/EH provides PGOOD indicator for easy

system sequence control. Full protection features are

also integrated in the device, including the cycle-by-

cycle current limit, OVP, UVP, input UVLO and OTP.

⚫ Input Undervoltage-Lockout (UVLO)

⚫ Over-Temperature Protection (OTP)

 RT6310E: Latched Mode OTP

 RT6310EH: Non-Latched Mode OTP

All above functions are integrated in a UQFN-23L 3x3

(FC) package.

Applications

⚫ Laptop Computers

⚫ Tablet PCs

⚫ Networking Systems

⚫ Servers

⚫ Personal Video Recorders

⚫ Flat Panel Television and Monitors

⚫ Distributed Power Systems
